Abstract: 862,521. Measuring electrically. UNION CARBIDE CORPORATION. Nov. 6, 1959 [Nov. 10, 1958], No. 37692/59. Class 40 (1) Apparatus for indicating the hardness of earth strata for controlling the operation of a mining machine, comprises a cutting tooth 1 on a shaft 2 resiliently held against the rotation urged upon it by the reaction of the stratum against the tooth 1, the amount of rotary movement of the shaft actually effected being a function of hardness of the stratum and being indicated as such by an inductive or capacitive transducer operatively connected with the shaft. As shown, the tooth 1 and its shaft are deflected against the resilience of a rubber cylinder 3 bonded to a fixed cylinder 9 and to a tube 3 to which the shaft 2 is splined at 4. The inner end of the shaft 2 has a flattened section which is disposed in the magnetic field of a rotary differential transformer 17, a variable resistor 18 being used to adjust the output of the transformer to zero when no torque is being applied. In a modification, Fig. 8 (not shown), the tooth shaft is hollow and co-operates with a coaxially disposed cylindrical torsion member, which can be adjustably prestressed, arranged within it, the deflection of the torsion member being communicated to the transducer proper by a coaxially arranged shaft. The electrical signals are used to control the mining machine and are also reproduced on the screen of an oscilloscope. In a second modification the rotary transducer takes the form of a variable capacitor consisting of a fixed plate and a plate which moves with the shaft 2 and varies the spacing between the plates according to the hardness, the capacitor being connected in the feedback circuit of a transistor oscillator, Fig. 6 (not shown), so that the oscillator output varies with the variation of the capacity and hence the strata hardness.

Abstract: 1,146,176. Expanding wheel gear; securing together rotary parts. COWLES DISSOLVER CO. Inc. 30 Aug., 1966 [20 Oct., 1965], No. 38606/66. Headings F2D and F2U. Relates to an expanding V-belt pulley variable speed gear wherein a driving pulley comprises an axially fixed half 14a and a half 14b axially movable for ratio variation, and a driven pulley comprises an axially fixed half 15a and a half 15b axially movable by compression spring means for belt tensioning. In such a gear, to enable the transmission of high power at low speed, the force of the spring means is increased and reduced respectively as the half 15b moves towards and away from the fixed half 15a. The driving fixed half 14a is fast on a hollow sleeve 17 axially screw-adjustably keyed on the shaft 11 of a constant speed electric motor 12. The driven fixed half 15a is fast on a shaft 13 which may constitute a final output shaft or the intermediate or countershaft of a multi-stage system. The axially movable halves 14b, 15b are axially slidably mounted on the sleeve 17 and the shaft 3, respectively, by pairs of self-lubricating plastics keys 26, 36 which are tangentially disposed so as to be put into compression and are anchored at their ends to the halves 14b, 15b. The driving movable half 14b is acted on for ratio variation by a hand wheel 49 acting through a telescoping screw connection 47, 46 (having screw-adjustable end stops 50, 51), a lever means 43, 56, co-operating outer and inner gimbal rings 59, (60), and an anti-friction bearing 66. The belt tensioning spring means comprises one or a pair of spring expanded telescopic links 75, the opposite ends of each of which are pivoted respectively to the end 77 of an arm 73 fast with the lever means 43, 56 and to the end 79 of an arm 74 of a lever means 74, 71 acting on the driven movable half 15b through co-operating outer and inner gimbal rings 59<SP>1</SP>, 60<SP>1</SP> and an antifriction thrust bearing 66<SP>1</SP>. Whilst the arms 56, 71 are of equal length, the arm 73 is twice the length of the arm 74, so that, during ratio variation, when the arms 73, 74 move with axial movement of the halves 14b, 15b the end 77 moves twice the distance moved by the end 79, with the result that the spring force increases as the half 15b moves towards the half 15a and vice versa. Each telescopic link 75 comprises a rod 76 pivoted to the end 77 and telescoping in a tube 78 pivoted to the end 79. A compression spring 72 engages at one end an abutment 81 fixed to the rod 76 and at the other end an abutment 82 screw-adjustable on a sleeve 83 fixed (e.g. welded) to the tube 78. Telescoping spring-support tubes 80a, 80b are respectively secured to the abutments 81, 82. Cooling fans 38, 39 are carried by the halves 14b, 15b.

Title: Production of foamed plastic products
Inventor: FITZPATRICK HUGH JAMES
IPC: B29C44/56
Filed: 1965-09-09
Abstract: A foamed polystyrene product having a hard outer surface, is produced by substantially filling a closable, heat-conducting, non-airtight mould with prefoamed expandable polystyrene pellets, heating the walls of the mould externally to a temperature sufficient to activate and expand the pellets and to liquefy those pellets which are in contact with the inner surface of the mould walls, and then cooling the mould.  The heating may be done in one stage by immersing the mould in a hot air bath at a temperature of at least 240 DEG  F., or it may be performed in two stages, first by immersing the mould in a water-bath to activate the pellets, but below their liquefaction point, e.g at 190 DEG  to 220 DEG  F., and then by immersing the mould in a sand bath above the liquefaction point of the pellets, e.g. at over 240 DEG  F.  The quenching should preferably be carried out immediately on completion of the heating.  The mould walls may be coated with a solvent for polystyrene which is volatile at the activation temperature of the pellets, e.g. with naphtha or with trichlorethylene.  Reinforcing or decorative material may be introduced and applied to the inner surface of the mould prior to the filling with polystyrene pellets, and may be in the form of woven fabric or may be particulate, e.g. silicate sand, or material may be added to increase the fire retardancy of the hardened surface of the product (e.g. asbestos fibres).
